^ After the invasion of Poland, the Germans planned to set up a Jewish reservation in southeast Poland around the transit camp in Nisko, but the "Nisko Plan" failed, in part because it was opposed by Hans Frank, the new Governor-General of the General Government territory. Adolf Eichmann was assigned to remove Jews from Germany, Austria, and the Protectorate of Bohemia and Moravia to the reservation. Although the idea was to remove 80,000 Jews, Eichmann had managed to send only 4,700 by March 1940, and the plan was abandoned in April. By mid-October the idea of a Jewish reservation had been revived by Heinrich Himmler, because of the influx of Germanic settlers into the Warthegau. Resettlement continued until January 1941 under Odilo Globocnik, and included both Jews and Poles. By that time 95,000 Jews were already concentrated in the area, but the plan to deport up to 600,000 additional Jews to the Lublin reservation failed for logistical and political reasons.
The workers who constructed the original buildings were housed in camps near Fallingbostel and Bergen, the latter being the so-called Bergen-Belsen Army Construction Camp. Once the military complex was completed in 1938/39, the workers' camp fell into disuse. However, after the German invasion of Poland in September 1939, the Wehrmacht began using the huts as a prisoner of war (POW) camp.
There were actually five satellite camps: a prison camp, a special camp for Jews holding papers from South American countries, a “star camp”—so called because prisoners had to wear yellow stars of David but not uniforms—for prisoners to be exchanged with the West, a camp for Jews holding citizenship papers from a neutral country, and a camp that housed 1,684 Jews deported from Hungary on a special train promised to Hungarian Jewish leader Rezső Rudolf (Israel) Kasztner. This last group was eventually destined for Switzerland.
The Dachau concentration camp opened on March 22, 1933. It was the first SS-run camp for "political prisoners" under Hitler's regime and became a model for the many SS prison camps that followed. Located in southern Germany, Dachau remained open until 1945 when it was liberated by U.S. troops. Approximately 200,000 people were detained during these years and an estimated 41,500 died.
Following the German invasion of the Soviet Union on June 22, 1941, Russian Prisoners of War were sent to Dachau. On Hitler's orders, Russian POWs who were determined to be Communist Commissars were executed at Dachau and other major concentration camps in Germany. The Communist Soviet Union had both political Commissars and military Commissars whose job it was to keep their citizens or soldiers in line. The military Commissars were stationed behind the front lines in order to urge reluctant Soviet soldiers forward since only one out of every 5 men had been furnished with a rifle. The Soviet soldiers were expected to pick up a rifle after another soldier had been shot; those who tried to retreat were shot by the Commissars. If captured, the Commissars were under orders to organize an escape or otherwise create havoc in the POW camp.
In March 1943, the Krakow ghetto was being liquidated, and all the remaining Jews were being moved to the forced-labor camp of Plaszow, outside Krakow. Schindler prevailed upon SS-Haupsturmführer Amon Goeth, the brutal camp commandant and a personal drinking companion, to allow him to set up a special sub-camp for his own Jewish workers at the factory site in Zablocie. There he was better able to keep the Jews under relatively tolerable conditions, augmenting their below-subsistence diet with food bought on the black market with his own money. The factory compound was declared out of bounds for the SS guards who kept watch over the sub-camp.
In August 1944, a new section was created and this became the so-called "women's camp". By November 1944 this camp received around 9,000 women and young girls. Most of those who were able to work stayed only for a short while and were then sent on to other concentration camps or slave-labour camps. The first women interned there were Poles, arrested after the failed Warsaw Uprising. Others were Jewish women from Poland or Hungary, transferred from Auschwitz. Among those who never left Bergen-Belsen were Margot and Anne Frank, who died there in February or March 1945.
